A further object of the invention is to provide an: improved and simplified process for imanufacturing thebrush; Y

Yet another object is to provide apparatus of the invention in a single operation. I I *The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth or be apparent in the following description of a preferred embodiment thereof and in the accompanying drawings, in which; Figure 1 is a front elevation of apparatus for producingthe brush, the'brush elements beingmounted' therein and the working parts of the apparatus being inoperatively disposed.

' I Figure 9'is an elevation of a brush charged --with soap and wrapped for vending, a portion of the wrapper being broken away. Referring particularly to Figures 5'to 9 inclusive, the brush 11 of my invention is Figure 6 is a view bf a pre-formed ferrule seen to be formed of a cylindrical bunch 12 of suitable bristles doubled intermediately to form a fold 13 which provides ahandle'for forming relation, a banding ring or a ferrule 15 is fixed about the doubled bristle bunch at the junctureof the handle and tuft portions of the brush. The completebrush is thenseen to be made up solely of the bristle bunch 12 and ferrule 15.

In providing the present brush, it is a particular purpose-t0 minimize costs whereby a brush may profitably be discarded after a the brush and to bring the bristle ends into I lateral uxtaposition to provide the brush tuft portion 14. For securing the bristles in brush single use thereof. For this purpose, the bristles used preferably comprise suitable vegetable fibres, such being very much less expensive than are animal bristles; ofthe available fibres, those of sisalhave been found particularly satisfactory for the purpose, both as to qualities of the tuft provided andthe cost thereof. For the aforesaid reason, the ferrule 15 is also of inexpensive material and structure and preferably comprises a closed and non-stretching ring of wire or cord; in the present instance, the ferrule 15 is formed of a length of stiff wire shaped to provlde a torus of a single strand of the wire, with the wire ends contacting but not necessarily fixed together.

The labor and apparatus involved in applying the ferrule to the bristle bunch to provide thebrush must also, of course, be a minimum, and the preferred method of the present invention is to provide the ferrule as a preformed element and engage the bunch'of bristles therein to form," the brush] by a single operation. The latter operation isefiected by forcing the intermediate portion of the bristle bunch transversely against-and axially through the ferrule to provide the handle loop and tuft portions of the brush, the ferrule compressedly fitting the doubled bristle bunch whereby a permanent structure results.

A preferred apparatus for carrying out the aforesaid process is disclosed in Figures 1 to 4 wherein the working parts of the device are carried on an upright standard or pedestal 16, mounted on a base 17. As particularly shown, upper and lower brackets 18 and 19 respectively are adjustably mounted on the standard at intermediate points thereof. The upper brack t 18 carries a plunger 21 for vertical reciprocation therein and said plunger is provided at the lower end thereof with a plate element 22 provided with a forked portion 23 its lower and free end. Preferably, and as shown, the element 22 forms a detachable part of the plunger whereby it may be removed for replacement.

The lower bracket 19 is formed to provide a horizontal shelf 2 1 axially underlying the plunger 21., and said shelf is provided with a perforation 25 into and through which the element 22 is arranged to be reciprocated from normally withdrawn position above it. The perforation 25 iscircular and is of no less diameter than the inside diameter of a preformed ferrule ring 15. Preferably, and as shown, the perforation 25 is counterbored from above to provide an annular seat 26 for the centered reception of a ferrule 15. The maximum width of the plunger fork 23 is such that said fork may pass downwardly into and through a ferrule 15 engaged in the seat 26.

It will now be noted that if a fibre bunch 12 be disposed laterally across a ferrule 15 engaged in the seat 26, the projection of the plunger fork 23 transversely against the bunch will force the engaged bunch portion aXially into and through the ferrule to pro vide the handle fold 13 and operatively enthe ferrule about the doubled bunch to provide the brush; Figures 3 and 11 CllS- close the plunger fork in its final brush forming position. With the present apparatus, I prefer to primarily mount a bristle bunch 12 in the raised fork, inserting it from below through the space provided below the fork,

18 shown in Figures 1 and 2. Upon a downward movement of the plunger, the bunch is first engaged laterally across the mounted ferrule and thereafter folded and forced through the ferrule as described. It noted that relative adjustment of the lu'acltets 18 and 19 arran ed to control both the loading clearance of the fork and the ion: 11 of the brush handle.

Reciprocation of the plunger 21 may be o cted by any suitable means, a pedall; operated lever mechanism being provided in the present instance whereby to leave an operators hands free for performing the necesa lever 28 pivoted to the standard 16 adjac. L the bet in t A lever 29 ful- C1 n.ed he top of the se o1. i ding portions of the overs 28 and 29 are connected by a link 31 whereby a depression of the pedal 27 effects a downward movement of the plunger 21 to form a brush, as described. A tension spring 82 connects the rear end of the upper lever 29 with a fixed element of the apparatus, as the bracket 19, to resiliently urge a restoration of the plunger to its raised position whereby such disposition of the plunger is arranged to be automatically effected when pressure on the pedal is released. As shown, a stop screw 30 is provided at the upper end of the plunger 21 for engagement with the bracket 18 to limit the downward movement of the plunger.

It is noted that if the fibre bunches 12 are engaged by the plunger fork at their exact centers, no trimming of the tuft of the brush produced will be required after formation thereof. While such is not shown, the use on the shelf 24, of a suitable positioning gauge for the pre-cut fibre bunches is seen as an obvious expedient for centerin said bunches in the fork. It is further noted that the bunches 12 are preferably pro-cut to length in any suitable manner from a continuous and relatively untwisted rope of fibre of suitable diameter; sisal fibre appears on the market in a loose rope form, which is the proper thickness for forming a shaving brush by the disclosed method, and since the sisal fibres have the desired brush bristle qualities their use is preferred.

After a completed brush has been removed from the plunger fork, it is preferably charged with shaving soap 33 by a dipping or other suitable process, and is then wrapped in a sanitary wrapper 34 for delivery, to a user. It is noted that the production of wrapped and soap-charged brushes in the manner now described, represents a minimum of manufacturin cost whereby they may profitably be discarded after being used once or twice. In this manner, the ends of convenience, sanitation and inexpensiveness are all served in the production and use of the present brush.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and method of use will be readily understood by those skilled in the art to which the invention appertains. While I have described the principle of operation, together with the device which 1 now consider to be a preferred embodiment thereof, it is understood that the device shown is merely illustrative, and that" such changes may be made when desired as fall within the scope of the appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent of the United States, the following:

Y
